Does MI5 take on psychologists

The UK's MI5 was renamed "Counter-Intelligence" years ago, so if you are still referring to MI5 then you are woefully behind the times.

Military Intelligence, the Secret Intelligence Service and Counter-Intelligence all make use of psychologists: to help interrogate enemy POWs or other enemy prisoners, to help debrief returning British POWs or other agents of the Crown, to help spread misinformation and Propaganda, to help turn enemy agents into double agents or informers, etc, etc.

Military psychologists tend to take safe roles away from areas of combat but they sometimes go out into the field. In fact, a female Military Intelligence officer on a river boat was killed by a bomb under a bridge in Iraq a few years ago. Does this put you off?
